High-speed operation of static binary frequency divider using resonant tunnelling diodes and HEMTs

A new circuit technology using resonant tunnelling diodes and HEMTs makes the toggle frequency f/sub toggle/ of a static binary frequency divider close to the cutoff frequency f/sub t/ of the used 0.7 /spl mu/m-gate HEMTs. f/sub toggle/ and f/sub t/ are 34 and 38 GHz, respectively. This technology is promising for use in high-speed logic circuits.
